Fix PG::GroupingError with label filters on MR analytics page
What does this MR do?
This MR fixes the PG::GroupingError
on the MR analytics page when more than 1 label filters are given.

How to reproduce it:
- Make sure you have ultimate license
- Make sure your project has at least two labels
- Go to a project and open the MR analytics page via the sidebar: Analytics > Merge request
- Filter by two labels
- See the 500 errors in the inspector (GraphQL request)
The fix should return 200 (success) response.
